(Mr Reithmaier)

I love the build up and tension before the start of a big race; here it’s the grid prior to the start of the New Zealand Grand Prix at Pukekohe, in the north of NZ’s North Island on 6 January 1968…

Chris Amon readies himself and his Ferrari Dino 246T before the first round of the 1968 Tasman Series, a race in which he wonderfully and deservedly triumphed. Missing on the front row is Jim Clark’s Lotus 49T Ford DFW. Car #2 is Pedro Rodriguez’ BRM P261, the Mexican is bent over the cockpit of his car but failed to finish with clutch problems. Car #7 is Alec Mildren’s Brabham BT23D Alfa Romeo T33 2.5 V8 with chief mechanic Glenn Abbey warming up the one-off car. Lanky Franky Gardner is adjusting his helmet beside the car, it was a good day for Frank, the car was second.

Look closely and you can see a camera crew behind the Brabham which is focusing on 1967 reigning world champion Denny Hulme and his #3 Brabham BT23 Ford FVA F2 car- Denny’s head is obscured by Frank’s body. Hume boofed the ex-Rindt BT23 during the race badly enough for a replacement chassis to be shipped out from the UK.

I’ve always thought these F2/Tasman Ferrari’s amongst the sexiest of sixties single-seaters. The 166 F2 car was not especially successful amongst the hordes of Ford Cosworth Ford FVA engined cars in Euro F2 racing. However, the car formed the basis of a very competitive Tasman 2.5 litre Formula car when fitted with updated variants of the Vittorio Jano designed V6 which first raced in F2 form and then owered the late fifties Grand Prix racing front-engined Ferrari Dino 246. It was in one of these cars that Mike Hawthorn won the 1958 World Drivers Championship.

Amon won the Tasman Series in 1969 with Ferrari Dino 246T chassis #0008 with fellow Kiwi Champion Graeme Lawrence winning in the same car in 1970 against vastly more powerful, if far less developed Formula 5000 cars. The story of those championships is for another time, this article is about Chris’ 1968 Tasman mount and campaign.

In many ways Chris was stiff not to win the ’68 Tasman, a title, the last, won by the late, great Jim Clark…

Ferrari entered only one car that year with chassis #0004 assembled in Maranello by longtime Amon personal mechanic Roger Bailey and tested at Modena in November 1967. It was then freighted by plane to New Zealand where it was assembled by Bruce Wilson in his Hunterville workshop in the south of the North Island.

The cars chassis was Ferrari’s period typical ‘aero monocoque’, a ‘scaled down’ version of the contemporary F1 Ferrari with aluminium sheet riveted to a tubular steel frame forming a very stiff structure. The 166 was launched to the adoring Italian public at the Turin Motor Show in February 1967.

In F2 form the 1596cc, quad cam, chain driven, 18 valve, Lucas injected engine developed circa 200bhp at an ear-splitting 10000 rpm. It is important to note that this F2 engine, designed by Franco Rocchi, and in production form powering the Fiat Dino, Ferrari Dino 206 and 246GT and Lancia Stratos is a different engine family to the Jano designed engines, evolved by Rocchi, used on the Tasman Dino’s.

The F2 166 made its race debut in Jonathon Williams hands at Rouen in July 1967, and whilst it handled and braked well it was around 15bhp down on the Cosworth engined opposition. Whilst the car was tested extensively at Modena, including 24 valve variants, it was not raced again that year.

Amon, who had not raced in the Tasman Series since 1964, could immediately see the potential of the car, suitably re-engined, as a Tasman contender given the success of the small, ex-F1 BRM P261 1.9-2.1 litre V8’s in the 1966 and 1967 Tasman Series. The same approach which worked for the boys from Bourne could also work in Maranello Chris figured. A parts-bin special is way too crass, but you get my drift of a very clever amalgam of existing, proven hardware as a potential winning car.

In fact Ferrari went down this path in 1965 when a Tasman hybrid of a then current F1 chassis was married to a 2417cc variant of the Jano 65 degree V6 for John Surtees to race in the 1966 Tasman. John had Tasman experience in Coventry Climax FPF engined Coopers and Lola’s at the dawn of the sixties and could see the potential of a small Ferrari.

That plan come to nothing when Surtees was very badly injured in a Mosport Can Am accident in his self run Lola T70 Chev in late 1965. This car, Ferrari Aero chassis ‘0006’ played the valuable role of proving Surtees rehabilitation when he completed 50 laps in the car at Modena. It was in the same chassis that Lorenzo Bandini finished 2nd in the 1966 Syracuse and Monaco GP’s as Ferrari sought to get the new 3 litre V12 F1 312 up to speed, Bandini electing to race the Dino on both occasions. He also finished 3rd aboard the car at Spa. The allocation of this more competitive car to Bandini rather than team-leader Surtees was amongst the many issues which lead to the confrontation between John Surtees and team manager Eugenio Dragoni during Le Mans practice and Surtees departure from the team.

An unidentified fellow, Jim Clark, Ferrari engineer Gianni Marelli, Chris Amon and Roger Bailey share a joke during the 1968 Longford weekend. Chassis ‘0004’ is fitted with the 24 valve V6 covered in the text. Note the quality of castings, fabrication and finish, inboard discs, sliding spline driveshafts and single plug heads of this very powerful- but less than entirely reliable engine in 1968 form, it’s shortcoming cylinder head seals (oldracephotos.com/Harrison)

The engine of the 166/246T was carried in a tubular subframe attached to the rear of the monocoque which terminated at the drivers bulkhead. The car was fitted with a 5 speed transaxle designed by Ingenere Salvarani and Girling disc brakes.

Suspension was also similar to the contemporary F1 cars in having an front upper rocker and lower wishbone with inboard mounted spring/shocks and conventional outboard suspension at the rear- single top link, inverted lower wishbone, two radius rods and coil spring/shocks.

For the 1968 NZ races- Chris won at Pukekohe after Clark retired and at Levin, leading from flag to flag, was 2nd to Clark at Wigram and 4th at Teretonga- a 3 valve variant (2 inlet, 1 exhaust) of the 65 degree fuel injected V6 was fitted which was said to develop around 285bhp @ 8900rpm from its 2404cc.

Chris crossed the Tasman Sea with a 9 point lead in the Series from Clark and the might of Team Lotus. It was a wonderful effort, whilst Ferrari provided the car free of charge, and took a share of the prize money, the logistics were of Chris’ own small equipe. And here they were serving it up to Gold Leaf Team Lotus with a couple of World Champions on the strength, plenty of spares and support crew.

For the four Australian races a 24 valve version of the engine was shipped from Maranello. Its Lucas injection was located between the engines Vee rather than between the camshafts and had one, rather than two plugs per cylinder. This engine developed 20 bhp more than the 18 valver with Chris promptly putting the car on pole at Surfers Paradise, a power circuit. He won the preliminary race and had a head seal fail whilst challenging Clark in the championship race.

At Warwick Farm he qualified with the 18 valve engine and raced the 24 valver having rebuilt it- they only had one of the motors. He was challenging both Clark and Hill in the race and then spun in avoidance of Hill who was having his own moment…he was 4th on the tight technical Sydney circuit.

At Sandown during the AGP, the pace of the car, and Amon, was proved in an absolute thriller of a race in which he finished 2nd to Clark- let’s not forget the best driver in the world driving the best F1 car of the era powered by the Tasman variant of the greatest GP engine ever- and took fastest lap.

As the team crossed Bass Straight from Port Melbourne on the ‘Princess of Tasmania’ Chris knew he had to win the Longford ‘South Pacific Championship’, with Clark finishing no better than 5th to win the Tasman title.

At Longford, still fitted with the 24 valve engine, which must have been getting a little tired, he qualified a second adrift of Clark and Hill. He finished 7th in a race run in atrocious conditions on the most unforgiving of Australian circuits having initially run 2nd to Clark but then went up the Newry Corner escape road and suffered ignition problems from lap 10.

Piers Courage won in an heroic drive aboard his little McLaren M4A Ford FVA F2 car that streaming day, in a series which re-ignited his career.

Chris was a busy boy during the Australian Tasman leg as he also drove David McKay’s Scuderia Veloce Ferrari 350 CanAm/P4 in sports car support events at each round in addition to the little Dino.

These races were outstanding as they all involved close dices between Chris and Frank Matich in his self designed and built Matich SR3 powered by 4.4 litre Repco Brabham ‘RB740’ V8’s- with Frank getting the better of him in each of these races. The speed of the Matich was no surprise to Chris though, both had contested rounds of the Can Am Championship only months before the Tasman in the US.

Amon lines David McKay’s Scuderia Veloce Ferrari P4/350 Can Am up for Longford’s The Viaduct during the 1968 Longford Tasman meeting. Matich didn’t take the SR4 to Longford so Chris had an easy time of it that weekend. The sight and sound of that car at full song on the Flying Mile at circa 180mph would have been really something! (oldracephotos.com/D Keep)

For the ’69 Tasman Chris applied all he learned in 1968 returning with two cars, the other driven by Derek Bell, four well developed 300bhp 24 valve engines with the logistics taken care of by David McKay’s Scuderia Veloce.

He promptly lifted the Tasman Cup in a very successful campaign from Jochen Rindt, Graham Hill and others. With a little more luck, or greater factory commitment in 1968 it may have been two Tasman’s on the trot for the Maranello team and Chris…

Surtees in his big Ferrari 312, a new F1 car built to the 3 litre formula introduced that year leads Jackie Stewart in his light, nimble BRM P261, a 1.5 litre F1 car bored to around 2.1 litres and shortly to be victorious over ‘Big Johns’ heavy and not so powerful Ferrari.

It may have been different if he had driven the light, nimble Ferrari Dino 246 allocated to teammate Bandini, but that was not to be and so the pressures mounted which lead to Surtees departure from the Scuderia shortly thereafter. And with it any chance Ferrari had of winning the title that year. Brabhams year of course.

Jackie Stewart’s BRM P261 is pushed onto the Longford grid by Jimmy Collins and Stan Collier on 5 March 1966…

The race is the ‘Launceston Examiner Trophy’, the preliminary Longford Tasman round race, Jackie is being pushed into ‘pole’. Jackie won the main race, the ‘South Pacific Trophy’ on the Saturday from his teammate Graham Hill and Jack’s Brabham BT19 Repco, the new ‘620 Series’ V8, 2.5 litres in Tasman spec having its third race gearing up for his successful world championship assault that year.

For the BRM boys it would be a more character building year, mind you, Jackie took a great Monaco GP win in his nimble 2.1 litre P261 against the new 3 litre GP cars…

The ‘Stack Pipe’ 1.5 litre P56 BRM V8 nestled in one of Graham Hill’s BRM P57/578 chassis’ during his and BRM’s victorious 1962 season…

This series of engines was immensely successful being competitive throughout the 1961-5 1.5 Litre F1 and was ‘stiff’ not to have won the title on multiple occasions. Later in its life it became, in 2 and 2.1 litre capacities an effective Tasman Series weapon. It was victorious at 2.1 litres against new 3 litre cars winning the ’66 Monaco GP Jackie for Stewart that May. It is one of Grand Prix racing’s great engines.

This is the first in an occasional series of articles focussing on engines, mind you, as usual its longer than intended. As is the case with most of my stuff the article is a function of a great photo (above) inspiring the piece rather than me thinking strategically about the relative merit of one engine to another in a particular era!

Background…

BRM commenced the new 1.5 litre F1 in 1961 by using a Coventry Climax FPF Mark 2 engine, it’s ‘Project 56’ 1.5 litre V8 started late and was running behind schedule.

The teams long serving but ‘too dilettante’ technical director Peter Berthon was ‘shunted sideways’, seconded to work at the Harry Weslake Research consultancy in Rye, 280 km away leaving Tony Rudd, his assistant in charge.

By the time this 1960 Dutch GP change was effected Berthon, with the assistance of consultant engineer Charles Amherst Villiers an old school friend of BRM founder Raymond Mays and a long term associate of Berthons too, was already laying down the conceptual design and detailing of P56. The Shell oil companies research boffins also contributed their knowledge via a project they were completing at the time on ‘combustion in high speed transport engines’.

Clark won the race in his Lotus 25 Climax (GP Library)

A core conceptual design foundation was efficiency at extremely high RPM by the standards of the time, and, for the first time for BRM the engine was to be offered for customer sale rather than just being a ‘works engine’. There was money to be made, as Coventry Climax had proved in recent years by flogging engines to those with the ‘readies’, at Sir Alfred Owen’s insistence BRM were to contest that customer market.

In keeping with the BRM charter of using British suppliers if at all possible, Lucas’ new fuel injection system was chosen. Several design features of the old V16 were used including its timing gear, camshaft drives and similar con-rods, higher inertia loads of heavier pistons (than the V16) involved different big-end bolt arrangements though.

The engine is a 90 degree V8 with a bore and stroke of 68.1 X 50.88mm for a capacity of 1498cc, it’s heads and block cast in LM8 aluminium alloy. The sump was magnesium and the crank machined from nitrided EN40U alloy steel and ran in 5 Vandervell, 2.5 inch wide plain metal bearings.

The cams, water pump and distributor for the transistorised ignition system were driven by gears off the cranks nose.

Two ring die-cast pistons and forged con-rods were used initially but forged pistons with a different profile were experimented with later in the successful search for more power. Results justified Berthon’s original concept of minimising rotating and reciprocating mass with a very ‘over-square’ bore/stroke ratio by the standards of the day to facilitate high RPM.

Up top the four cams ran in 5 roller bearings operating 2 inclined valves per cylinder via inverted tappets. Valve sizes were 1.5625 inch inlet set at 45 degrees from the bore axis, and 1.20 inch exhaust set at 30 degrees. Double valve springs were used and proved effective even at 11000rpm, the valve-gear was designed for a maximum of 13000rpm.

The Lucas new fuel injection system was of the port type, throttle slides were used after early butterfly throttles were tried and rejected. The compression ratio using mandated 100 octane fuel was 11.5:1. The fuel injected works engines claimed 10bhp more than the Weber carbed customer units in the first year. The metering unit was driven by a toothed rubber belt.

Lucas also provided the transistorised ignition system made necessary by 11000 rpm; a conventional coil setup produced around 400 sparks per second, a magneto 500 whereas the BRM needed 733 sparks per second at 11000 rpm, which the Lucas transistors achieved.

Ignition timing was controlled by pole pieces mounted on the back of the flywheel in conjunction with a magnetic pick-up on the engine backplate. Current was provided by an alternator driven from the right-side inlet cam.

P56 in Trevor Taylor’s BRP Mk2 BRM, Belgian GP, Spa 1964. 7th in the race won by Clark’s Lotus 25 Climax (Schlegelmilch)

The prototype P56 engine ‘5601’ was assembled at Bourne in June 1961, without starter motor weighing 251 pounds, on 12 July in the Folkingham Aerodrome test house it first burst into life.

A second engine was built and run at Monza, in practice only in 1961. That engine ‘5602’ produced over 184bhp. During 1962 maximum power was 193bhp@10250rpm, the engines dyno curves showed 110@6000, 150@7500, 173@9000 and 190bhp@9750rpm.

At Monza in 1962, Hills victorious P578’s P56 engine achieved 10.6 MPG.

Graham Hill’s 1962 season is briefly covered in this article, click here for the link; https://primotipo.com/2014/10/12/graham-hill-brm-p57-german-gp-1962/

Initially the engines were fitted with separate individual megaphone exhausts raking back at near to vertical on each side but they fatigued during a race and progressively broke. A low level system made its debut at Spa in 1962 but by then the ‘Stackpipe BRM’ label had stuck!

A cross-over exhaust and ‘flat plane crankshaft’ liberated a bit more power as did new Shell low viscosity oils, by February 1963 the works engines gave 200bhp from 9750-10500rpm.

Four valve heads were tried for 1964 but ‘flopped fearfully’. Reversed port two valve heads and between the Vee exhausts at the Italian GP provided 208bhp @10750rpm.

Eventually by filling combustion chambers with weld and re-machining, trial and error stuff engine ‘5618’ produced 220bhp@11750rpm this engine was used by Hill at the 1965 BRDC Trophy and became his regular engine thereafter ‘maxing’ at 222bhp.

For the sake of completeness the ‘P56 engine family’ also includes the P60 used in various capacities for 2 litre sportscar, endurance, Tasman and hillclimbing competition as follows;
1965/6 1880cc, 1966 1916cc, 1966-7 1998cc and 1966-8 2070cc.

Jackie Stewart heads for the BRM P56 engines last championship GP win in his P261, 22 May 1966 Monaco. He won from Lorenzo Bandini’s Ferrari Dino 246 and teammate Graham Hill’s P261. Majestic Monaco. The BRM P261 was an exquisite, successful, long lived car. It was slippery and quick partially due to power but also the small, beautifully ‘packaged’ engine, its between the Vee exhausts and compact ancillaries allowing the rear cowling which helped it slip thru the air (Schlegelmilch)

Race Record…

The P56 and its big P60 brother was a remarkably long-lived engine at International level, let alone its national level wins.

The engines first International win was in the rear of Graham Hill’s BRM P57 in the 1962 Brussells GP on 1 April, its first Championship GP win the Dutch on 20 May 1962, its last Jackie Stewarts 1966 Monaco GP victory in 1966 amongst the new 3 litre GP cars. Jackie Stewart also scored the engines last International win in taking the Australian GP at Warwick Farm on 19 February 1967 in his BRM P261.

P60 engine now at 2070cc, the ‘weak link’ of the car by then the transmission which was struggling with power and torque for which it was not originally designed in 1.5 litre GP spec  (Mike Feisst)

The engines final entry as a ‘works engine’ was in the back of Pedro Rodriguez’ P261 at the Longford Tasman round in March 1968, he was second to Piers Courage McLaren M4A FVA.

During that period the engine won the ’62 Drivers and Constructors titles with Hill. Hill/BRM were second in both the drivers and constructors titles in ’63 to Clark/Lotus in ’64 to Surtees/Ferrari and in ’65 to Clark/Lotus. The BRM P261 won the 1966 Tasman Championship for Jackie Stewart in a dominant display, BRM won 7 of the 8 rounds.

For the sake of completeness the wins for the engine, note that i have not included heat wins in Non-Championship events, only ‘Finals’ are as below, what comes through strongly is just how much Hill.G’s career was intermixed with this engine and how smart it was to sell engines to ‘all-comers’;
